I doubt that surprised anyone, like I said, they were blantly just wrongly wired and it was always going to happen, and I very much doubt that its possible to EVER undo the harm that was done to them, so they will almost certainly always present a danger to society.

The real shame IMHO is that no one was held accountable for WHY they are like that, I certainly wouldnt have just randomly done that sort of thing at 10 years old as I was brought up correctly, I genuinely believe that with any young children who commit crimes the parents should be held at least partly accountable, although I have no idea how you would implement such a system.
The thing is though, very few people seem to want to learn anything from this case, look at the outbursts from the likes of "t4 and greys" in this thread as an example, if people have that over simplified attitude of just deciding the boys were evil and not giving a fuck about why, how do we prevent this sort of criminal failing in the upbringing of children from happening again?
